To all whom it may eminem:

Bc it. known that I.' SAMUEL S. Yaniuno- 'romacitiven of the United States of America, residing at Wilmington, in the county of Newcastle and. State of Delaware, have invented new and useful Im rovemeuts in ('ntaularans, of which the ollowing is a specification.

This invention relates to catamarans, the

object of the invention being to provide a nos-l and improved central platform which is rielriinglv supported on the iarallel shells so that the shells und the plat orm are relativev movable, thus accommodating for thc desired movements of the platform on its sudden contact with the waves.

A stilll fui-thor object of the invention is to construct the said platform of a suhstan. *tinlly opcnwork frame whiclrwill permit the water to be forced therethrough on contact of the platform with the waves to prcvent such action of the water against the platform 4:from retsrding the movement of fthe vessel. v I' 'In the drawings, forming a rtion of this specilication and in -wlncli Ii e `numerals of reference indicate similar arts in the several vivra-Figure 1 is a p an viewof my improved catamaran. Fig. 2 isa side view thereof. Fig. 3 is a deta longitudinal section through the platform showing a part of one of the shells 1n full lines. Fig. 4 is a. detail transverse section taken on the line 4-4 of Fig. 1. Fig. 5 is a detail section taken on the line 5 5 of Fig. 1. Fig. 6 1s a detail section taken on the line 6-6 of Fig. 1. Fig is a detail section takenon the' line 7 7 of Fig. 6. Fi 8. is a vertical section through` a portion o one of thc rndders.

Mv improved catamaran consists of iden. tically formed parallel shells 1 which are formed preferab y of hollow metal members constnicted to form non-communicating weer chambers or compartments 2, each of such compartments bein provided with an inwardly opening chec valve 3 through which the desired air pressure may be forced into the shell. From this construction it. will be seen that the shells sie extremely buoyant and sinking of the vessel is imposible. Near the fron end the shells are connected together by the brace 4 which com risesmembers 5 on the shells, the tie rod which connects the members with each other and the double turn-buckle 7.' The platform 21 is vwhich are mounted in besri member 8. of the tnrnbuclrle is supported by the standard 9 which extends upwardly from thetie rod 6. The extremities of the member 8 are threaded and they are spaced l0- from the threaded extremities of the meme bers 10 of the txirnbuckle so that the odin cont ends are operatively associated to sccoinmodater the adjusting nuts 11. The outer ends of' the members 10 are secured to the members 5 as particolari shown in l-i -1 of the drawings. Each s ellis r0- vii ed on its underside with a suitable 12. Near the rear ends the 'shells are connedled with each other by afbrace 13 which is substantially idcntical'n constructionwith the licrcinlieforc described brace 4, the diercnce being in the provision ofa depending movablymounted frame 14.. The frame 1 is formed to provide o oke 15 in which the 76 sleeve-16 is mounted. e sleeve 16 is pr()- vided with lateral pins 17 which extend through the elongated slots 18 in the yoke. The shells areprovided with front vertical 'pins 19 and' rear vertiml pms 20.- A 60 provided at the center of the vessel and as illustrated, it consists of a rectangular frame .which is foi-ined of the longitudinal side bars 22 and the Vend bars 9.3. The bars 23 are connected with each 86 other by parallel spaced slats 24. The bars 22 are connected with each other by the parallel slats 25. This forms s platform of openwork construction for a purpose to be hereinafter described. The end bars 23 are 90 extended beyond the longitudinal side bars and formed in each extended ortion is an elo ted slot 26. The slott extremities of t e bars 23 lit over the vertical pins 19 and 20 on theshells 1, and as illustrated l5 particularly in Figs. 3 and 4 of the drawings, elical extensible springs ogsuivslent elsstic elements 2T Aare intcrp between the shells and the platfo When springs ereemployed they are preferably coiled about 10 the vertical pins 19 and 20. A cross moinber 28 is mounted beneath the platform and its ends are formed to provide trunnions 29 30 on the shells.` A-rnotor 31 is conventionally shown 105. in the drawings This motor is suitably mounted on the platform 21 at s' point immediately in front of the seat.l 32. The (propeller shaft 33 of the motor extends ownwardly thronleih-the frame and itsproller'84 is loca -at s point immediato! weon the shells. The propeller shaft extends thi-ou h the sleeve 16 so as to re siiilicicntly from the platform to prevent its tends through the up l Castel of this `patent my be obtained for contacting with the water.

Each shell is rovided at its rear end with siiperininsed rings 89 between which the rud er 4G is movably mounted. The rudder is provided with an intermediate squared passage 41 which receives the correl y formed shank 42 on the ruddercontrollin member. The shank 42 is provided witg a depending cylindrical stem 43. which extends through the lower bearing 39. The shank 42 sirovided with an u ivardly extending oylin rical bearing 44 w ich exper bearing 39. Cotter pins or like fastenings 45 extend through the stems 43 and 44 at points outwardly of the bearings. It mayy be stated that the o ening'n the hearing 39 is slightly greater t an the diameter of the shank 42 `and that immediately above the opening and mounted on the stem 44 and a `a point below the uppermost cotter pin 45 is a washer 46 whose opcninq3 is less than tho one formed in the spondin upper 'eating 39. Wheii it 4 is desired to remove the rudder the towel-most cotter pin is disengaged from the valtern 43 and Vthe shank 42 can be removed by'drnwing the same u wardlv until it is entirely free from the ru der. a uppermost stems 44 of the rudder Shanks are provided with crank arms 47. The arms of each shank .are operativelg' connected with the controlling cables 4 These cables are connected with the windin drum 49 wlicli is' mounted in a suitib e bracket 50 which extends upwardly from the rounding the said pins.

platform at s point in advance of the operators seat. A suitable steering wheel 61 is operatively connected with the drum.

'The construction of 'the catamaran as described and disclosed herein is extremely simple and will be found moet durable in that by providi the Yieldinaly supported p lntorm the she s wil be r eved o considerable strain and the platform will be relieved of considerable wear and tear. By constructing the platform of the herein described cross slats `the waves when striking the bottom of the platform will otter little or no resistance in the travel of the vessel as it will be seen that the water can make its escape by way of the passages 52 between the slats of the platform L A catamaran comprising spaced shel bearings extending upwardly from each shel midway-hetween the ends thereof, s, lat form having trunnions mounted in the arings, the sind platform' including end meinbers havin ,elongated slots therein, vertical pins exten ing upwardl from each shell and extendin through e slots in the said platform, an sprin inte osed between the platform and she s respec ively und sur- 2. A catamaran comprising spaced shells, bars connecting the shells with each other, a platform mounted for rocking movement on the shells and comprising a substantiall reticulated structure including front'v an rear liars having portions extended beyond the sides of Vthe platform and formed to provide elongated slots, pins extending upwardly vfrom each shell, and s rings interposed between the said outwa ly extended portions of the front and rear bars and between the shells respectively.

In testimon whereof I atiix my signature in presence o two witnesses.
